I can't say for the whole EU, but in our small county vacuum apparatus is i hard thing to get without additional questions. So, I had to buy a Büchner on eBay.
Another problem was a pump. I know, some people use the car air compressor slightly modified. But I found another solution: electric vacuum pump made in China - AJK-B12A2801, much much more elegant and compact.
This is a pump that, according to the manufacturer, is used for ventilators and similar medical equipment.
Power source: DC 12V, 750mA
Vacuum pressure: <70 kPa
Volume: >4.5L/min
The manufacturer promises at least 700 hours of work.
Exit connector presents, so you can plug it to the hood easily.
Such pump you can easily buy via Ali Express.
Even I have proper hoses specified for as vacuum, for the tests I decided to use normal silicone hoses 8/12 and 4/8, and accompanied with filter 7 - 10 µm work perfectly.
The pump, power adapter AC 220 to DC 12, hoses emptied my wallet for 20 EUR.
For the Bunsen with 10mm exit you need 8mm hose.
Regards.
